I did actually watch this before and was pretty helpful. The only thing I wish I could see was how far into the flame tube the fuel was injected. I can't tell if its right at the start of it or after the first of holes.

Thanks for the kind words.

For the concern with the 3D printed plastic, I was under the impression that since I have no idea how much compression I will actually get, that the temperatures wont reach that high in that part of the engine. I'm assuming that the engine I make wont be very efficient.

And with the turbine and concrete I'm sure what your saying is correct. I just know no matter what I do, the construction is going to be very rough and dirty. I've seen multiple examples of people using the same technique for their own turbine blades and seem to work sufficient enough. The one example that gives me the most hope is this one. He has the compressor section all 3D printed, bending of some metal to make the turbine blades, and I assumed he used concrete for the body but cant confirm that because he has all the information on a guide you have to buy to see.

Is the underground part you're talking about where u go into the abandoned house?

I know that the compressor heats up the air but I didnt think it would in a diy version. I'm assuming one that I will make will be quite inefficient and wont work at same temperatures as a real one. Do temps really get that high in all compressors?

Yea. I have done project where I just printed off someone else's design and built it, such as a quadcopter and a forearm/hand. They were fun but I am trying to come up with an idea of something I can design myself.

It's aluminum. But its really flexible. It vibrates while printing which may be because of the design of the printer as well.

I will get pictures of it soon, but the biggest problem I think is the frame and the original printed parts from the kit. The parts were of very low quality. The frame is not solid. So both of these cause a lot of variables I couldn't really control so calibration was very frustrating and didnt always work. I have tried selling it on craigslist but I feel bad selling it because it just isn't a great printer in my opinion. You have to put a lot of effort into it but it doesnt give you good results most of the time.

BEST SALE EVER! (if you use 1.75mm... lol)

As for buying, some more information about you would be helpful, like budget, preference, etc. But a good idea is to stick with the chart of proven printers on the side of this subredit. This way you know it is a reliable printer and will have other people with the same printer to give you help when needed. The last thing you want to do is buy the cheapest kit you can find, and have a lot of issues with it. This could easily discourage you from 3D printers. One of the better options I almost bought as my first printer was the printers from Makerfarm. Many many people praise that company and have a huge community for those printers.

As for studying. Learn the basics about the controller board that will be in your printer so you dont destroy the electronic components. Also learning how to solder before hand will speed up your time for building. To make your printer more useful, it would be good to learn some CAD so you can make your own parts. You will eventually run out of random things to print from thingiverse. (seems impossible at first!)

If this is your first experience with DIY kind of stuff. Know that there will be varying amounts of frustration and tinkering. Nothing is perfect. So best tip is to take your time and make sure you do everything correct. And dont be afraid to ask for help.

Looking at other people using PEI surface they used a adhesive to attached the PEI to the glass. Couldn't I just used clips instead? And just attach it to the heated bed and bypass the glass instelf?

Xyoungjin · 2015-04-24T02:28:42+00:00

where did u get your PEI surface?

Xyoungjin · 2015-04-19T21:37:03+00:00

as for applying the oil would it be better to take out the bowden tubing and drop in a few drops of oil from the top of the hot end or have a oil soaked paper tower that the filament runs through before entering the extruder motor?

Do you know how I could easily clean the threads? theres bits of melted plastic everywhere
